Mechanical Drawing for Stratix V DSP Development kit?

Yeah i did download the kit installation. There is a PDF with a mechanical drawing of the device on it but it uses an unconventional method to provide the dimensions. So i was hoping for another source, as like a second opinion, as i'm only guessing at how they've decided to display the information. The drawing doesn't give any form of measurements for the centre of the holes.

I've attempted to open the gerber file using 3 online websites and Eagle but all of them give me an error message saying that there is something wrong with the gerber file. So it appears like i'm not able to view the file.

For me this is an important decision because i'll be buying a new computer for this application, so i want to make sure before i buy something that needs match the requirements.

Here is the mechanical drawing i talk about. Would anyone say that the corner that i've coloured red and put an arrow to is the origin of all of the measurements? The holes are indicated with the letter 'K'.
